Problems solved by technology

The existing verification method of 7816 receiving data to wake up Standby is limited to GPIO, system clock and other signal marking, and it is necessary to use an oscilloscope to observe the signal waveform. The verification environment is relatively complicated to build, and the verification efficiency is low, and it is impossible to verify the card packaging samples.
[0007] 2. The existing verification technology is only applicable to pre-Tapeout verification, not to post-Tapeout test
[0008] Since the waveform of the system clock signal needs to be observed, and the clock signal cannot be obtained during the post-Tapeout test, the post-Tapeout test is not applicable
[0009] · Low verification efficiency
[0010] Verification requires the use of an oscilloscope. It takes a long time to set up the verification environment and the verification process, and the efficiency is low.
Multiple cycle verification is less efficient

Abstract

The invention relates to a verification method for using a 7816 interface to wake-up a smart card chip Standby, which realizes the verification of smart card chip entering Standby mode and receiving data to wake-up Standby mode through 7816 interface. The invention has the characteristics of intuitionistic, convenient and quick wake-up process, , and no other auxiliary equipment is needed.

Description

technical field [0001] The invention relates to a verification method for waking up a smart card chip Standby mode by receiving data through a 7816 interface, which is used for the pre-tapeout verification and post-tapeout testing stages of the smart card chip. Background technique [0002] In the pre-Tapeout verification and post-Tapeout testing of smart card chips, the time spent on building the verification and testing environment often accounts for a high proportion of the total verification time, and once the verification test environment is ready, the actual time spent on chip verification testing is not much . The existing verification method of 7816 receiving data to wake up Standby is limited to marking GPIO, system clock and other signals, and needs to use an oscilloscope to observe the signal waveform. The verification environment is relatively complicated to build, and the verification efficiency is low, and it is impossible to verify the card packaging samples. ...
